Abstract

The invention provides highly conglutination resistant, high temperature resistant and environment-friendly water-based preprinting gloss oil. The water-based preprinting gloss oil is prepared from, in percentage by weight: 50-65% of high temperature resistant water-soluble acrylate copolymer, 2-5% of nano zinc oxide dispersion emulsion, 5-10% of fluorosilicone modified wax emulsion, 0.2-0.6% of flatting agent, 10-40% of deionized water and 5-10% of cosolvent. The main component of the highly conglutination resistant, high temperature resistant and environment-friendly water-based preprintinggloss oil is a water-based substance, and is harmless to human body. As an environment-friendly product, the water-based gloss oil not only can endow the packaging surface with the good glossiness, meanwhile can meet the requirement for 160-220 DEG C laminating temperature of corrugated cases in the preprinting and polishing processes, and overcomes the defects that existing conventional acrylic resin water-based gloss oil can bear a low laminating temperature, the coating hardness is low, the after-tack resistance is poor, the waterproof performance is poor, and the adhesive force is poor. The invention further provides a preparation method of the highly conglutination resistant, high temperature resistant and environment-friendly water-based preprinting gloss oil.

Description

technical field [0001] The invention relates to the technical field of pre-printed varnish, in particular to a highly anti-blocking, high-temperature-resistant and environment-friendly water-based pre-printed varnish and a preparation method thereof. Background technique [0002] Printing varnish is generally applied in the last glazing process in the paper printing process to improve the decoration and functionality of printed products. At present, there are three main types of varnishes on the market: solvent-based, UV-curable and water-based. The use of solvent-based varnishes has been gradually reduced due to serious air pollution; UV light-curable varnishes are difficult to promote due to complex processes and high one-time equipment investment costs; water-based varnishes have strong transparency and good gloss , folding resistance and other advantages, using water as the diluent, safe and environmentally friendly, so the popularity is getting higher and higher.
